There had been a drought where many of the Pueblos starved causing it to be hard for them to work and offer food to the Spanish, they were led by a shaman named Pope. They destroyed the colonies and regained their land, however the alliance fell apart and they started to fight each other.
I hope this helps.

Are you asking for some examples of challenging the color barriers? if so then some examples are the Little Rock Nine trying to desegregate schools, and the Greensboro Four who sat at a counter in a diner marked only for whites and they were harassed but they were always polite.
The system of the government consists of 3 branches, the Legislative, Judicial, and Executive. The judicial branch deals with whether things are constitutional or unconstitutional, and takes court cases that have been passed on from other parts of the government. the Legislative branch contains the congress. The executive branch carries out laws and has the president and vice president.
